CEL plays peek-a-boo.

[ZenkiKid]

eversince my car has recieved a new EGR, new connection to the MAF, new cat, and new 02 sensor, my CEL has been playing peek a boo at random times. Ive noticed that at around 3k, it commonly appears. I havent had any running problems at all though, what could it be?

any of those above mentioned things could cause the CEL.
so its hard to determine with the information provided what the problem is

Mine was playing peek-a-boo for a few months before it decided to fully stay on.

Luckily, my buddy's a Nissan tech. So, he ran a diagnostic(free of charge) and told me I was running rich and needed a new O2.

There's a thread that tells you how to clean out your intake manifold as well.

Let me link you to it...

That was also the cause of my CEL popping up.

Try it out and see if it helps.

what I did to keep mine form coming on was take the bulb out of the dash.

It's always good to ignore the problem:loco:
